UN aid convoy hit by drone strikes in Ukraine's Kherson
A UN humanitarian convoy delivering aid to Kherson was hit twice by drones on 15 May, according to the supplied report.
The convoy had been coordinated in advance with both Ukrainian and Russian forces.
No injuries were reported in the incident.
The UN has not attributed the attack to either side.
The strike matters because it affected a protected aid operation in an active conflict zone.
Humanitarian convoys are typically arranged to reduce the risk of attack and allow supplies to reach civilians.
Kherson has remained a sensitive area in the war, and aid deliveries there depend on access arrangements that can be disrupted quickly.
The reported drone strikes raise fresh concerns about the safety of humanitarian movements.
The available information does not say what damage, if any, was caused to the convoy or whether the delivery was completed.
